Automatic dimming glasses and control method thereof

Abstract

The present application discloses an automatic dimming glasses, comprising a liquid crystal lens, a plurality of sensor units and a driving circuit, the liquid crystal lens includes a lens body and a liquid crystal layer located between the lens bodies, the plurality of sensor units are used to acquire images, the driving circuit and the A plurality of sensor units are connected to detect the pupil image in the image acquired by the sensor unit, obtain the light intensity information of the incident light and the front view angle information according to the pupil image, and provide corresponding information to the liquid crystal lens according to the light intensity information and the front view angle information. The liquid crystal lens controls the deflection of the liquid crystal molecules in the liquid crystal layer according to the control signal, so as to realize the automatic adjustment of the light transmittance of the glasses, so that the light intensity entering the human eye is always in the most comfortable range, which protects the human eye very well .

Description

technical field [0001] The present invention relates to spectacles, and more specifically, to an automatic dimming spectacles and a control method thereof. Background technique [0002] With the development of society, excessive light radiation has caused adverse effects on human life and production environment, and "light pollution" is threatening people's health. For example, during the day, reflections from mirrored buildings can cause dizziness to pedestrians and drivers, threatening the health of pedestrians and drivers, and unreasonable lighting at night can also cause discomfort to other drivers, and may lead to traffic accidents in severe cases. [0003] In order to avoid the damage of excessive light intensity to the human eyes, people nowadays often wear sunglasses to block the strong light when they are doing outdoor activities or driving, especially in strong light environments, so as to reduce the fatigue caused by eye adjustment. and glare to the eyes.

AI Technical Summary

Problems solved by technology

[0004] Most of the existing sunglasses use tinted lenses. The color of the lens determines that the lens can absorb the corresponding light in the spectrum. Although it can block the damage of strong light to the eyes, it will also block part of the light in a weak light environment. , aggravate the burden of eye adjustment, which has a counterproductive effect and has certain safety hazards
